【 摘 要 】

To improve the quality of woven embroidery products, it is necessary to improve the ability of embroidery to prevent pilling. The monofilament bundle is impregnated with 2% polyvinyl alcohol and crosslinked and cured by microwave heating at a suitable power. The finished silk samples are characterized by infrared spectroscopy and X-ray powder diffraction, scanning electronmicroscopy and optical microscopy. The experimental results show that after the monofilament bundle is heated by 350W microwave power for 4 minutes, the degree of aggregation of the finished monofilament bundle is greatly improved, the chromaticity of the sample is not significantly decreased, the silk feel is soft, the tensile strength is slightly enhanced, and the anti-friction ability is obviously enhanced. On this basis, further optimization of the process conditions may provide technical support for the anti-pilling finishing industrialization of products such as embroidery.
